Unirse stares PATENT] 7 To all whom t may cof/wem:

Be it known that l, WiLLiAM Jr. a citizen of the United States, residing at hiladelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improve-v ments in Safe or Vault Doors, of which the following is a specication. I

My invention relates to improvements in safe or vault doors wherein the boltwork of the locking devices is carried by a plate of comparatively soft or machinable metal secured to the main body portion Vof the door which is formed of relatively hard or nonmachinable metal, such as manganese steel.

The object of my invention is to improve the means to secure the boltwork plate to the body portion of the door and to provide a securing means which shall not only be simple, inexpensive, and eflicient, but shall be inclosed and confined within the main body of the door.

With the above and related objects in view, the invention consists in the novel construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings illustrating my invention,

Figure 1 is a view of a safe door embodying my invention, as seen from the interior of the safe and partly broken away and partly in section.

`Fig. 2 is a section through the door, on line 2 2 of Fig. 1.

Fig. 3 is a view of the sectional locking member.

Referring to the drawings, 3 designates the main body portion of va door which is formed of extremely hard and tough metal, preferably a casting of manganese steel. The body portion 3 comprises a front wall 4 having an annular rim 5 projecting rearwardly therefrom and an annular flange 6 projecting inwardly from the rim 5 in spaced relation to the front wall 4. The periphery of the rim 5 is suitably shaped to t against the jamb or wall of a safe or vault when the door is closed against the same.

The rear or inner wall vof the door comprises a plate 7 which is formed of relatively soft or machinable steel so that parts thereof may be properly machined or finished to re- H. HoLLAR,.

Specification of Letters Patent.

ceive Yparts of thel boltwork" of ythe. leclng devices for the door, whichthe plate is adapted tov carry. :The platel 7 isprovided with two inwardly-extending annular flanges 8 and 9 through which ancircularseriesl of radially eXtending' locking bolts 10 extend. The bolts 10 are slidably fitted to the flanges y8 and 9 and they are adapted to be projected into and retracted from locking position by suitable mechanism not shown in the drawings. The boltwork or locking mechanism may be similar to that shown and described in Letters Patent No. 621,341, dated March 21, 1899.

The main body of the plate 7 vis fitted within the fiange 6, and the plate 7 has an outwardly-extending annular flange or lip 1 1 which is seated against the fiange 6 and rim 5., as shown. Suitable dowel pins 12 are provided which extend through the flange 11 and into the rim 5 and prevent circular displacement of the plate 7 relatively to the main body 3 of the door.

Jarranged between the plate 7 and the forward wall 4 of the body 3 is an annular sectional locking member 13, formed of a circular series of segmental plates 14 which permit the entire locking member 13 to be contracted to be passed through the flange 6 to a position within thezrim 5 and thereafter expanded to engage'the flange 6 between it and the front wall 4, in assembling the parts. When the locking member 13 is thus expanded, the sections 14 thereof are secured to the pla-te 7 by suitable screws 15 and 16 which extend through the plate 7 The hollow body portion 3is filledwith concrete in which may be embedded suitable burglar and fire proof elements such as the plate 17 of manganese steel, the plate 18 of non-burnable metal and the steel rods 19 shown in the drawings, the whole forming a ysolid door structure inclosing 'within the lbody thereof the means which secures the Patented Feb.' 22, 1921.

Application filed June 20, 1919. Serial No. 305,548.

Y 'sa boltwork plate 7 to the manganese casting 3 which forms the frame or main body portion of the door. p

I claim as my invention y l. VIna safe door, a body portion having a front wall, a rim, and an inturned flange on the rim, a plate, and a looking member separable from and secured to the plate and extending between the front wall and the flange and preventing movement of the platel from the body portion.

2. In a safe door, a body portion having a .front wall, a rim, and an inturned flange on the rim,. a;p1ate, and a locking member separable from and secured to the plate, 'said flange extending between the plate and the locking member. f l

3. Ina safe door, a body portion, a plate,

front wall, a rim, and an inturned flange on the rim, a plate, a sectional looking member comprising a circular serles of independently movable sections, and means to secure the sections of the member to the plate said flange extending between the plateV and the looking member.

In testimony whereof, I afiXrmy Signature hereto.
